Three-four alternator coil winding with associated heat sinks

摘要

The stator of the alternator has a delta winding with each winding having twelve coils. Three diode bridges are provided with each bridge being connected to the junction of two of the windings. Each bridge has four positive diodes connected in parallel and four negative diodes connected in parallel. Two of the positive diodes of each bridge and two of the negative diodes of each bridge are connected to a first output member and the other two positive diodes and the other two negative diodes of each bridge are connected to a second output member. Two heat sink plates are connected to the inside of one wall of the alternator housing and a third heat sink plate is connected to the outside of the wall. Each plate supports diodes from three of the bridges.
